摘要：This paper uses new data on the removal of local, sector-specificbarriers to firm entry across 1,800 municipalities in Peru to estimate theimpact on firm productivity and markups. New legislation in 2013 strength-ened the national competition authority's mandate to enforce the elimi-nation of local entry barriers, providing a quasi-experimental setting toidentify the impact of competition on productivity within the controlledinstitutional environment of a single country. We find that the elimi...

摘要：The production of knowledge relies on collaborations between researchers. However, we do not know to what extent policies may stimulate these interactions. In this paper we show how a large-scale public research cluster policy in France, which funds local communities of researchers working on a common theme, affects the organization of research. Relying on an identification strategy based on grades awarded by reviewers, we show that members of financed clusters increase their collaborations wi...

摘要：We examine how physician decisions are affected by difficult cases-encounters with newly diagnosed cancer patients. Using detailed administrative data, we compare primary care physicians' decisions in visits that occurred before and after difficult cases and matched comparison cases by the same physicians on other dates. Immediately following a difficult case, physicians increase referrals for common tests, including diagnostic tests unrelated to cancer. The effect lasts only for about an hour...

摘要：Using quasi-random variation from Facebook's entry to college campuses, I exploit a natural experiment to estimate the effect of online social network access on future earnings. I estimate that access to Face-book for an additional year in college causes a .62 percentile increase in a cohort's average earnings, translating to an average wage increase of around $970 in 2014, and decreases income inequality within a cohort. I provide indirect evidence that wage increases come through the channel...

摘要：The low rate of inflation observed in the United States over the past decade is hard to reconcile with traditional measures of labor market slack. We develop a theory-based indicator of interfirm-wage competition that can explain the missing inflation. Key to this result is a drop in the rate of on-the-job search, which lowers the intensity of interfirm-wage competition to retain or hire workers. We estimate the on-the-job search rate from aggregate labor-market flows and show that its recent ...

摘要：The percentage of U.S. homes heated with electricity has increased steadily from 1% in 1950 to 40% in 2020. Energy prices, geography, climate, housing characteristics, and income are shown to explain 90% of the increase, with energy prices by far the most important factor. The paper then estimates the cost of an electrification mandate for new homes. Households in warm states tend to prefer electricity anyway, so would be made worse off by less than $350 annually on average. Households in cold...

摘要：Factorial designs are widely used to study multiple treatments in one experiment. Although t-tests using a fully saturated long model provide valid inferences, short model t-tests (that ignore interactions) yield higher power if interactions are zero, but incorrect inferences otherwise. Of 27 factorial experiments published in top-five journals (2007-2017), nineteen use the short model. After including interactions, more than half of their results lose significance. Based on recent econometric...

摘要：We experimentally study procurement auctions when both quality and price matter. We compare two treatments where sellers compete on one dimension only (price or quality), with three treatments where sellers submit a price-quality bid and the winner is determined by a scoring rule that combines the two offers. We find that, in the scoring rule treatments, efficiency and buyer's utility are lower than predicted. Estimates from a Quantal Response Equilibrium model suggest that increasing the dime...

摘要：We investigate the impact of peer interaction on the quality of fi-nancial decision making in a laboratory experiment. Face-to-face commu-nication with a randomly assigned peer significantly improves the qualityof subsequent private decisions even though simple mimicry would havethe opposite effect. We present evidence that the mechanism involves gen-eral conceptual learning (because the benefits of communication extend topreviously unseen tasks), and that the most effective learning relations...

摘要：We conduct a natural field experiment with a major European party to test whether giving party supporters more voice increases their engagement in the party's electoral campaign. In the experiment, the party asked a random subset of supporters for their opinions on the importance of different policy areas. Giving supporters opportunities to voice their opinions increases their engagement in the campaign as measured using behavioral data from the party's smartphone application. Survey data reve...
